JOHN G. LAMPMAN, OF HASTINGS, MICHIGAN.

CLOTH E-S-POUNDER.

SPECIFICATION forming part of Letters Patent No. 247,071, datedSeptember 13, 1881.

Application filed July 8, 1881. (No model.)

To all whom it may concern:

Be it known that I, JOHN G. LAMPMAN, of Hastings, in the county of Barryand State of Michigan, have invented an Improvement in Clothes-Founders,of which the following is a specification.

The nature of this invention relates to certain new and usefulimprovements in the construction of clothes-pounders; and the inventionconsists in the peculiar construction and arrangement of parts, as morefully hereinafter described.

In the accompanying drawing, which represents my invention as a centralvertical section, and which forms a part of this specification,Arepresents a cone, made of sheet metal, of such character as will notrust, and at its apex it is provided with a socket, a, to receive aproper handle or shaft.

B is a diaphragm dividing the hollow cone into two chambers, the upperone, 0, being a tight chamber and having no communication with the outerair. The socket a extends down drawing, and the apex of the invertedhollow cone is cut off on the line of the base of the cone A. Theinverted cone, secured as described, converts the lower ehamber, E, ofthe cone A into an annular conical-shaped chamber, as shown. Tubes bafl'ord communication with the outer air from the interior of theinverted cone, passing through the diaphragm B and the walls of the coneA.

By this construction and arrangement 'a break in the air current andpassage is had, by which a more free ingress of air is obtained withoutthe egress of water, as would be the case if the air-tubes 1) extendeddownward through the walls of the inverted cone D, or if the latter wereremoved.

The construction herein described prevents suction.

What I claim as myinvention is- A hollow conical elothes-pounder dividedinto three chambers by means of a diaphragm and inverted cone, andprovided with air pipes b, aflording communication between the interiorof the inverted cone and the exterior of the head, substantially asdescribed.
